The procession will then head north on Michigan Avenue to inner Lake Shore Drive, then west on Division Street, north on LaSalle Boulevard, north on Clark Street, north on Sheffield Avenue, west on Addison Street followed by a lap around Wrigley Field.

Santo spent 15 years in Major League Baseball – playing third base for the Cubs from 1960 to 1973, and one more season with the White Sox in 1974. He joined WGN-AM 720 radio as a Cubs color commentator in 1990, and had planned to return to his post there next season.

Santo was a longtime diabetes patient and lost two legs to amputation, but he helped raise millions of dollars to support Juvenile Diabetes research. He died of complications from bladder cancer in Arizona on Dec. 3.
